No April Fools' Day Joke: 439 of Oregon's Bridges Need Structural Repair, New Analysis of U.S. Department of Transportation Data Finds

Federal Highway & Bridge Funding Facing May 31 Deadline

WASHINGTON, April 1, 2015 /PRNewswire-USNewswire/ -- An analysis of the recently-released 2014 U.S. Department of Transportation (U.S. DOT) National Bridge Inventory database finds there are more than 61,000 structurally deficient bridges in need of significant repair all across America.  And it is a problem that hits close to home.

The analysis of the federal government data, conducted by American Road & Transportation Builders Association (ARTBA) Chief Economist Dr. Alison Premo Black, shows cars, trucks and school buses cross Oregon's 439 structurally compromised bridges 1.5 million times every day.  Not surprisingly, the most heavily traveled are on the Interstate Highway System, which carries the bulk of truck traffic and passenger vehicles.

The top 10 most heavily traveled structurally compromised bridges in the state are:

  1. I-5 (Highway 001) over Jantzen Pedestrian Tunnel (Multnomah County)
  2. Multnomah Boulevard over I-5 (Multnomah County)
  3. I-105 (Highway 227) over Future Highway 62 (Lane County)
  4. 1-105 (Highway 227) over the Willamette River (Lane County)
  5. OR-99E (Highway 001E) over the Union Pacific Railroad (Multnomah County)
  6. Highway 69 WB over the Willamette River and River Avenue (Lane County)
  7. OR-22/Highway 30 WB over the Willamette River (Marion County)
  8. Highway 69 EB over the Willamette River and River Avenue (Lane County)
  9. Tacoma Street over the Willamette River (Multnomah County)
  10. I-5/Highway 1 over Hillcrest Drive (Josephine County)

The bridge problem could get a whole lot worse soon, Black warns.  The federal Highway Trust Fund (HTF) is the source of 52 percent of highway and bridge capital investments made annually by state governments.  The HTF has suffered five revenue shortfalls between 2008 and 2014, and has been bailed out with nearly $65 billion in revenues from the General Fund just to preserve existing investment levels.  The latest extension of federal highway and transit funding through the HTF expires on May 31, absent congressional action.  Nearly a dozen states so far have canceled or delayed road and bridge projects because of the continued uncertainty over the trust fund situation.  ARTBA expects that number to increase as the deadline nears.

"State and local governments are doing the best they can to address these significant challenges, given limited resources," Black says.  Bridge investments have been growing in recent years, Black says, but it has come at the expense of highway and pavement spending, which has dropped over 20 percent in the last five years.

"Without additional investment from all levels of government, our infrastructure spending will be a zero-sum game," she said, noting that there is a current backlog of over $115 billion in bridge work and $755 billion in highway projects, according to U.S. DOT data.

"Many of the most heavily traveled bridges are nearly 50 years old.  Elected officials can't just sprinkle fairy dust on America's bridge problem and wish it away," Black said.  "It will take committed investment by legislators at all levels of government."

Bridge decks and support structures are regularly inspected by the state transportation departments for deterioration and are rated on a scale of zero to nine—nine being "excellent" condition.  A bridge is classified as structurally deficient and in need of repair if its overall rating is four or below.

While these bridges may not be imminently unsafe, ARTBA believes that signs should be posted so the public understands they have structural deficiencies that need repair.

The ARTBA analysis of the bridge data supplied by the states to the U.S. DOT also found:

  • Oregon ranks 33rd place nationally in the number of structurally deficient bridges—439.
  • Oregon ranks 42nd place in the percentage of its bridges that are classified as structurally deficient—5 percent.

State specific bridge information from the analysis—including rankings and location lists of the 250 most heavily travelled structurally deficient bridges in the nation and top five most heavily travelled in each state—is available at

Established in 1902, the Washington, D.C.-based ARTBA is the "consensus voice" of the U.S. transportation design and construction industry before Congress, the White House, federal agencies, news media and general public.
